The historical development of bearings

2023-09-12

The early form of linear motion bearings was to place a row of wooden poles under a row of skid plates. Modern linear motion bearings use the same working principle, but sometimes use balls instead of rollers. The simplest rotary bearing is a bushing bearing, which is just a bush sandwiched between the wheel and the axle. This design was subsequently replaced by rolling bearings, which replaced the original bushings with many cylindrical rollers. Each rolling element was like a separate wheel.

Whether the bearing is installed correctly affects the accuracy, life and performance.

Whether the bearing is installed correctly affects the accuracy, life and performance.Therefore, the design and assembly department must fully study the bearing installation. Hope to install in accordance with operating standards. The operating standard items are usually as follows:

How to ensure the reliable operation of the bearing

The bearing clearance should be appropriate. If it is too large, it will cause impact, if it is too small, it will be poorly lubricated and may burn bushes;

The sealing of the bearing can be divided into two types: self-sealing and external sealing.

The sealing of the bearing can be divided into two types: self-sealing and external sealing. The so-called bearing with its own seal is to make the bearing itself into a device with sealing performance. Such as bearings with dust caps, sealing rings, etc. This kind of seal occupies a small space, is convenient to install and disassemble, and the cost is relatively low.
